wynjammer: mustang dyno vs. dynojet

i had my truck first dynoed on a mustang dyno at a local shop, it put down 220hp and 228ft/lbs. at school we have a dynojet, i was driving by one day this week and offered me the dyno. how could i say no? so i thought it would interest some at the results. btw, i go to school at the university of northwestern ohio. its a very cool school.





239hp and 250ft/lbs. the first run was a bad run, ignore it. when i take that class i plan to have some tuning software so i can tune it.

Re: wynjammer: mustang dyno vs. dynojet

Awesome results bro. We are making similar HP here. This here proves those Mustang dynoes underrate HP. That's like a 19 HP gain from the dynojet. Glad to see these results. I was worried there when you said 220 rwhp before. Now I know why.

Re: wynjammer: mustang dyno vs. dynojet

Nice results. So it looks like 8psi is equivalent to a 75 shot, your 8psi numbers, track and dyno, are similar to mine.

you have more torque then me...: ( i think i did a bad job on my heads. i think my current suspension setup is holding me bad some too. my best 60' are 2.1 this year. all well.

Nitrous usually makes more torque than boost. When I ran 8.7 I was at a 1/8 mile track, I later ran 13.9 at a 1/4 track on a shitty weather day. Its interesting to see you have more power, me more torque, but still run similar times.

ive only been here for a session, so i dont know about everything here. but the dorms are crap, i live off campus. im in the same thing your goin for. the open house really isnt that good, i went for a personal tour so i could see the kids workin on stuff. overall its not bad.

Do they provide off campus housing, or do you have to pay everything yourself?

they dont provide off campus housing, the dorms are really expensive for what they are. i pay a lot less then i would for a dorm, and i have my own room and 2 kids i trust to live with. i suggest looking online at some places around the school you'd be interested in taking a look at while your up here. give them a call and set something up. the dorms are way crowded too, 6 people, one bathroom...a little gay.

Re: wynjammer: mustang dyno vs. dynojet

Very nice numbers.

My truck put down 225hp/290tq on a mobile Dynojet with my set up on 5 psi.

Re: wynjammer: mustang dyno vs. dynojet

Ive been on both. At work we have a Mustang, so I did all my tuning and engine build using one. I have found that the Mustang is usually closer to real world. But that is my opinion. What where the temp, pressure, and humidity differences? They do make a good amount of differance

when i was on the mustang dyno it was prob 75*-80* out and a bit more humid. it was the end of june. it was prob 60* out on the dyno jet and it didnt feel that humid, but its been raining here in ohio a lot for the past few weeks. i noticed when on the mustang dyno that when they did the power pull, the truck was running at 210. it never runs that hot, on the dyno jet, i pulled it at like 190, or something a lot cooler. im sure there are tons of factors that make the difference.

your intercooled arent you? and yours is tuned. everyone seems to have more torque then me. what are some reason why i might be making less then everyone else? you do have great numbers for 5 pounds.

Re: wynjammer: mustang dyno vs. dynojet

I made about 222 rwhp, 250 rwft/lbs at 7 psi on a dynojet. I was running meth injection at the time but it was spraying too much. I tinkered with it later and it felt stronger but I doubt it would have made that much of a difference at the rear wheels anyway. We're usually at about 4300 ft density altitude here.

Will gearing make a difference in rear wheel torque readings? It seems like it could be a factor but maybe it's corrected for somehow? Rob8284 - those are great rwft/lbs numbers compared to most of the regular S/C'd guys.

My run was in the dead of summer around 85 ˚ and 70% humidity.

I don't have my intercooler on, nor do I have a very good tune done. I have it running richer then it should be, so I could get a little more out of it if I spent the time to put a good tune in (which I need to find the time to).

Thanks. I don't know if the dyno was lying to me, but I think it runs pretty good for what it is so far.



This winter, I should be sending out my head unit to have it upgraded and rebuilt to the new Si-Trim by Vortech instead of the old/outdated A-Trim I am currently running.

Re: wynjammer: mustang dyno vs. dynojet

dyno jets normally read higher than mustang dynos. Mustang dynos are called the heartbreaker for a reason, but they are more realistic. The dyno jet calculations tack on a little extra.

Nice numbers

Re: wynjammer: mustang dyno vs. dynojet

MUSTANG DYNOS ARE NOT UNDERRATED. they are exact. you can calibrate the dyno to say whatever you want. you can put down 200whp on the first run, with a few clicks of the mouse you can put down 220whp. it is a number contest so people want to see the highest numbers. we own a mustang awd dyno. (brand new). we did very heavy research when we bought a dyno. Land and Sea dynos are built in my home town. but they read to high. we want a low reading dyno (accurate). so when our low number car beats your high number car. we are not crying.

we did 1/4 mile runs with numerous cars on our dyno day last week, and all said they were exact to within 10th of a second to what they really run. (obviously your not gonna run the same time over and over)

when it comes down to it. if my evo 9 puts down 450 on a mustang dyno, and i race a STI that puts down 500whp on a dyno jet. and i win. whos crying now? but kids just want to see high numbers.

Re: wynjammer: mustang dyno vs. dynojet

i base whats fast and whats not off of quarter mile times, not dyno numbers. i compare my dynojet numbers to kids at school that have had there car on the same dyno. on the mustang dyno they ran my truck in the quarter mile, it came up a 14.8, its off...

Re: wynjammer: mustang dyno vs. dynojet

Usually a mustang dyno is 10% lower in hp rating than a dynojet. I know this because I used to run with a 1g and 2g GSX group. We would go to the performance shop with the mustang and I would run 356 hp and then we would go to speedtech which we knew the owner and I would run 35 hp more. I don't know though I think there is a difference in all the different models of dynos. I need to put my blazer on one before I put the new motor in.

Re: wynjammer: mustang dyno vs. dynojet

now when you dyno yours at 356whp, and your keepin up with the 395-400whp 1g's. the other drivers will be impressed by you, and disapointed in there own car at the same time. its a big number game. or you have a 365whp evo the runs the 1320 in low 12's and your buddy cant get into the 12's with 365whp(dynojet numbers)

in a recent test. Speedfactory's SRT-8 challenger claims 700 crank hp. so it should put about 670whp. not close it put down 454whp on a dynojet. the higher the hp the claim, the more of these cars they will sell. <<< thats kinda besides the fact (but i like laugh about that as much as i can)

its all preference tho, if you dont race and have a show truck and you want to claim the big numbers like 350whp out of a 4.3L, then go for it.

sure when i was 16 and my 2005 evo 8 only put down 295whp at 22psi with stage 2 bolt ons, i was pissed. i shoulda been puttin down 320whp, yeah on a dynojet i woulda put 320. but it felt good to beat my buddies 320whp sti's.

Yeah I miss my dsm days but oh well marriage changes a lot of stuff. I love the blazer now. Just costing more to fix up. I am glad I found a good forum to find out a lot about the motor performance wise.

yeah i know what you mean, i have a 700whp 2.1L 67mm turbo evo 9, and i just sold my 07 silverado, and got a 2002 s10 zr-5 crew cab, that is MINT. and i didnt know you could do so much to them, motor wise. maybe ill try a 20g or something on a 4.3L next year lol

Maybe you should stop bragging about "your 700whp Evo" on a S10 board already.

And btw, my 800whp WRX would kill you.
